Subject: [PATCH 29/40] perf tools: Add dso__data_get/put_fd()
Date: Mon, 18 May 2015 09:30:44 +0900 [thread overview]
Message-ID: <1431909055-21442-30-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1431909055-21442-1-git-send-email-namhyung@kernel.org>
Using dso__data_fd() in multi-thread environment is not safe since
returned fd can be closed and/or reused anytime. So convert it to the
dso__data_get/put_fd() pair to protect the access with lock.
The original dso__data_fd() is deprecated and kept only for testing.
